    Abstract: Energy Dispersive X-Ray Fluorescence (EDXRF) is a non-destructive analytical method used to solve problems involving nutritional, mineral, and toxic chemical elements. It is very common in the customization and commerce of jewelry. EDXRF depends on recording spectral lines from the irradiation of isotopes. After a brief review of the interactions o... Show More

    Abstract: This publication treated the determination (qualitative) and the quantification (quantitative) of the steroidal and flavonoids constituent molecules in the Strychnos spinosa pips. These molecules were extracted by esterification between the Strychnos spinosa pips and citric acid molecules in a reflux assembly such as the evaluated total moles of th... Show More

    Abstract: Biodiesel is generally believed to be the fuel to replace fossil fuel which has impacted the environment adversely. High pump price of biodiesel is one of the reasons why it is yet to replace petrol diesel. Edible seed oil and homogenous nature of the catalysts used are some of the reasons for the high cost of biodiesel. Some of the best ways to re... Show More
